To all whom it may concern: i'

Be it known that l, HERMAN G. DOEIJ JIN- can, a citizen of the United States residing at Davenport, in the county of Improvements in Candy-Dip ing Machines,

of which the following is a all, clear, and

exact description.

My invention relates to candy dippingbenches or tables, and more partlcularly to means for facilitating the work of a gangpipes :12, into which latter steam is fed from of operators dipping chocolate creams.

The object of my inventlon is to provide a machine of this character which enables a number of operators to work on opposite sides of a table-like structure; to obtainthe soft chocolate from the revolving member of the mixing and heating vessel without requiring the use of the fingers to scrapethe chocolate therefrom; to provide trays which can be easily removed and cleaned and to so construct these that they possess a supply pan separate from the parts of the. tray in which the dipping is done; to provide means for conveying the dipped chocolates slowly to and through a cooling chamber in which the chocolate coating is hardened, and to otherwise construct said machine so. as to avoid unsanitary conditions and to facilitate the work of the operators, substantially'as hereinafter fully described, and as particularly pointed out in the clalms.

In the drawings Figure 1 is aperspeetive View ofthe upper part of my invention. Fig. 2 is a plan view thereof, drawn to a slightly larger scale, of the dipping portion of the machine. Fig. 3 is a transverse section on a still larger scale, taken on dotted line'33,- Fig. 2. Fig. 4 is a side elevation of my improved machine with a portion of.

the cooling chamber broken away. Fig. 5

is a longitudinal section of the cooling chamber broken away from the remainder of the machine. Fig. 6 is a-plan view of a modified form of saidtray. Fig. 7 isan end view thereof. Fig. 8 is a transverse section of a portion thereof taken on dotted line 8-8, Fig. 6. Fig. 9 is a detail view. g

Referring to the drawings, A represents the bed or top of a bench or table, which is suitably supported by legs, and has a suitable longitudinal platform a supported centrally above it by suitable legs that extends from one end of the machine to a point, 'pref-.

' I spasms]. of Letters Patent.

cott and- State of Iowa, have invented new and useful 1- between its sides, substantially as'show'nthe drawings. Midway between the longitudmalsides of top A' it is provided with one or more sunken heating and mixing ves- 'sels B in which the chocolate is kept in a melted condition, the body of which'nonsists of an inner and outer metal shell and end-walls of one thickness of metal so as to provide a steam-jacket which is supplied with hot waterby suitable valve-controlled Bend the upper closed ends of the steamjackets thereof are flanged outward and are supported by andsecured to the table, and

the closed ends of the water-jackets are provided with faucets c. The water from these jackets is drained by pipes D that lead down from the lowermost segment thereof, and discharge into a suitable return pipe. d,

and the contents of the vessels may be removed therefrom by the gates s in the endwalls thereof, as shown. Y

vIfdesired, water could be supplied to the interior of said -water jackets and heated by means of a suitable gas burner, which latter is suppliedwith gas from a suitable service pipe ea Should this result-in too high a temperature to obtain: the best results with the chocol'ate,the flame ofthe burner canbe easily regulated by a valve e, substantially as shown in Fig. 3 of the drawings These vessels are covered by a segmental coverF the top of which describes a segment of a .circle, the radius of which is the same as that of the bottqm of vessels B so that when placed over the vessels the two form 'a substantially cylindrical receptacle the axis of which is transverse. V

The end-walls; of vessels 'n are provided with suitable bearings and a transverse shaft G is' journaled in these bearings that driven by a suitable worm-gear f thereon and a worm g-loosely mounted on alongitudinally extending drive-shaft HQ The motion of shaft H is transmflttedto worm -g by a Ion-Y gitudinally reciprocable clutch h, which lat ter is splined to shaft. H and has a longi- .tudinally ,reciprocablemovement thereon,

but revolves therewith; This clutch I k is moved into and out of engagement with its counterpart the adjacent end of worm g revolve the periphery of their rims receive a veneer or coating of chocolate, and heretofore the candy dippers either used their fingers or a knife blade and scraped the soft chocolate off the upper segment of the rim into a pan placed alongside the vessel in such position as to catch the drippings. I remove this soft coating or chocolate from the periphery ofthe rim by means of doctors 70 consisting of oblique scraping blades secured to the underside of the tops of the covers F, next the end-walls of the same,

which are so disposed as to engage and scrape the chocolate off of the rims. The chocolate drips into chutes K that are chairnel-shaped, and pivoted through the me dium of suitable lugs in openings in the end-walls of the covers so that they can tilt inward or outward to dump the chocolate drippings from the rim of the wheels back into the vessel, when inclined in one direction, or into the receiving-pan of the trays located alongside of the covers, when 1n-- clined in'the opposite direction.

The top of the table on either side of the vessel B extends in the same horizontal plane as the central portion thereof to the sides of the same, but beneath these side por tions I make longitudinal runways 1 that extend the entire length of the table. These runways are inclosed on the outer side by the side rails 2 of the table and on the inner side adjacent vessels B by longitudinal dropwalls3 secured to and depending from top A. The lower edges of the side-rails and the drop-walls are connected by a suitable bottom plate 4 and said runways are divided into upper and lower passages by a deck 5 comprising a horizontal partition that connects said side-rails 2 and dropwalls 3 the entire length of the table. These passages are designed to accommodate an endless apron'or belt that passes around a suitable'drive-roller 9 at one endof the machine that is mounted upon a transverse shaft 7, and. around asuitable idle-roller 8 at the opposite end of the machine. The upper stretch of this. apron is supported. by

and moves over the deck 5 and the sag of the under-stretch thereof 'moves over and is supported by the bottom plate'of the runway. Theffill'er of 'thechocolate creams when dipped are placed upon this apron, or

rather upon oiled paper placed upon it, and

These wheels in order to enable the operators to do this, the top A of the table over the upper passage of the runway is cut away or removed at suitable intervals to provide rectangular hatchways or openings 9 down through which the, operators can reach to deposit the confections upon the LPI'OIIS-' I prefer to provide the inner and transverse edges of these hatchways with suitable beads and to recess the said rails 2 of the table downas faras the deck 5 for the accommodation of the movements of the hands of the operators.

It is immaterial in sofar as the novel features of my invention are concerned what means are'employed to revolve shaft This shaft is mounted in longitudinally-adjustable bearings 10 supported on suitable brackets to enable the apron to be tightened when necessary, and I prefer to drive said shaft through the medium of a worm-gear 11 secured theretoabout its center oflength, and a longitudinally disposed worm 12 the shaft of w'hichzn isjdriven through themedium of a sprocket and chain 13,.which latter is actuated by gearing on shafts H and 15, substantially as shown in the drawings.

The chocolate melting vessels and dippingcontrivances, hereinbefore described, occupy about one-half the length of the table. Between the portion of the table devoted to said purposes and the opposite end of the same, the runways are entirely inclosed and form cold air ducts, and at one end of these inclosed portions-or ducts theflattened ends 16 of bifurcations 17 of an 'air exhaust-pipe 18, exhausts the air therefrom, and at the-- other end thereof cold air is supplied thereto from any suitable means through the 'medium of pipe 21, and the bifurcations 20, 20, extending from said pipe. 1

The apron 6 is extended beyond the discharge end of the-cold air ducts of the runway, substantially as shown in Fig. 5 of the drawings, and the confections are easily removed from said aprons by an operator seated adjacent thereto.

The trays, hereinbefore referred to, are placed on each side I ofthe mixing-vessels and comprise two corresponding rectangular Siamese platforms 22, 22, of a widthcorresponding to the Wldth".0f1'.tlle I runways.

These trays are connected bye-abridge or receiving-pan 23-which is :bfiset toward the vessels and forms a troughinto whichtthe soft chocolate dripsfrom the overhanging chute K before being swept intothe dippingtrays. The central portion 240i the inner longitudinal edge of the receiving-pan '23 is offset toward vessels B, and is designed-to enter a horizontally elongated slot 25in the ends of the covers of said vessels justabove the plane of the top of the table. The edges of the receiving-pan and the dipping trays are flanged upward, but where the receivmgpan mama the atygjthe. :fl ange i omitted so as to leave afgat'eway through the table with the o setof pair 23 in sl'ot25 of the cover F, hatchway 9. will be located to the right of each tray placed on the right side of the table, and to the left of each tray on the left side of the table so as to facilitate the work of the operators.

InFigs. 6, 7 and 8 of the drawings, I show a modification of the trays in which said trays 26 are made separate'from the receiving-pan'27. Jlhe edges of the tray 26 are provided with unbroken upward flanges and the receiving-pan 27 is constructed sub stantially similar to pan 23, except that it is separate from said trays and is surrounded on all sides with upwardly projecting flanges, except where it communicates with trays 26. At this point it is provided with a downwardly inclined lip 28 made by an extension of the bottom of the pan, that is adapted to lap over the adjacent flanged edge of the trays.

One or more of the operators can be seated on each side of the table, when my improved machine is in operation, and when it is desired to obtain a suficient quantity of melted chocolate for dipping purposes, the chutes K in the ends of the covers F are inclined outward and discharge the chocolate dripping from the periphery of the wheels J onto the receiving-pan 23. When a suflicient quantity of the melted chocolate is accumuv lated on this pan, the operator sweeps it onto the tray 22 and then takes the hardened cream or candy filler from a 7 box conveniently placed in front of him on the table and dips the same in the soft chocolate in said trays. He then deposits the dipped candy on the endless-apron 6 by which the candy is slowly conveyed to the discharge endof the runways. As the dipped candy reaches the inclosed part of the runways 1 it enters and passes through the cold air ducts thereof and is subjected to a current of cool air, and by the time it has reached the discharge end of the machine, the chocolate or other coating in which it is enveloped is hardened, and the candy is 'removed from the apron andv deposited in boxes by an operator seated at the end of a table for that purpose.
